FRIDAY, May 22, 2020 (HealthDay News) – COVID-19 has not increased the risk of stroke, but when a stroke occurs it is more likely to be fatal, according to a new study.
According to the researchers, less than 1% of patients hospitalized for COVID-19 suffer a stroke. But they also found that people with COVID-19 who have a stroke are seven times more likely to die than people who have a stroke but who are not infected with COVID-19.
"Our study suggests that stroke is a rare but important complication of the coronavirus, since these strokes are more severe compared to strokes that occur in patients who tested negative for the virus," said the lead researcher, the Dr. Shadi Yaghi, in a story from New York University. launching. He is an assistant professor in the neurology department at NYU Grossman School of Medicine in New York City.
For the study, Yaghi and his team identified 32 stroke patients among more than 3,500 who were treated for COVID-19 in NYU hospitals between March 15 and April 19.
They compared these patients with stroke patients without the virus. The researchers found that stroke patients with COVID-19 had more severe symptoms than those without the virus. During the study period, 63% died, compared to 9% of those without the virus and 5% of those who had a stroke before the pandemic.
These findings add to the evidence that COVID-19 is associated with an increased risk of clotting, which can trigger a stroke, the researchers said.
"Our findings provide compelling evidence that generalized blood clotting may be an important factor leading to stroke in COVID-19 patients." said study co-author Dr. Jennifer Frontera, a professor in the NYU department of neurology.
"The results point to anticoagulant or anticoagulant therapy as a potential means of reducing the unusual severity of strokes in people with the coronavirus," Frontera added in the statement.
The report was published May 20 in Stroke magazine.
